    I know this is really basic, but how do I forward any connection to
    port 3999 to IP (internal)?

    It seems difficult to do and I'm dazed and confused and in fear of
    messing the router up I decided to seek advice here before trying
    anything out.

    Is it something like this?
    access-list 100 permit tcp any host eq 39999

    Do I need to type anything in besides user and pw before typing this

    Thanks for any help :)

    Something like

    ip nat inside source static tcp 3999 interface Dialer0 3999

    From the information you gave me I managed to figure out "show run",
    there I saw some ports that are already forwarded (done by the admin
    (that cost's hundreds of $$$ to get him to do this for me)).

    From there I see its done like this:
    ip nat inside source static udp 39999 [my internet IP]
    39999 extendable

    However I already added the line you kindly suggested, now I'm
    wondering how to get it out there? :)

    Sorry, about the previous post, I meant to say:

    How do I remove the line from the config?
